Application filed. February 24, 1913. Serial N 0. 750,327.

To all whom it may concern Be it known that I, FREDERICK G. SAR- GENT, a citizen of the United States, residing at lVestford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Carrier for lVool-Vashing Machines, of which the following is a specifieation.

This invention relates to a carrier suitable for use in ordinary wool washing machines, and the principal objects thereof are to provide an improved support for the free end of the carrier to guide it with the least amount of friction, and also to guide it accurately so that the teeth will come into proper relation with the carrier table and roll; to provide means whereby the free end of the carrier can be adjusted vertically to regulate the distance of the teeth from thecarrier table, and means whereby the end teeth of the carrier that come nearest to the rolls can be adjusted on the carrier to pro ride for operation on long or short fibers as the case may be.

T he invention also involves improvements in details of construction for carrying out these objects, as will appear hereinafter.

Reference is to be had to the accompany ing drawings in which Figure 1 is a perspective view of a portion of a wool washing machine showing a carrier therefor constructed in accordance with this invention; Fig. 2 is a side view of a portion of the carrier showing the end teeth adjusted for operation on short fibers; and Fig. 3 is a similar view showing the end teeth in position for use on long fibers.

The wool washing machine or bowl 10 is provided as usual with a carrier crank shaft 11 operated by a pulley 12. This crank shaft is provided with a crank as usual to which are pivoted the ends 13 of two iron arms ll which constitute the supports of the carrier. These arms extend along the carrier to the end thereof and then project upwardly at 15. Their upper ends 16 are curved over and provided with guides 17 on the bottom which are shown as flat but as making a definite angle with respect to the body of the carrier and the direction of the arms 14, being inclined downwardly toward them so as to elevate the free end of the carrier gradually, but in a straight line, as it comes up toward the rolls. These guides rest on a palr of flanged wheels 18 which are mounted to rotate loosely on a non-rotatable shaft 19. This shaft is fixed in hubs 20 cast at the top of a pair of Vertically adjustable stands 21 mounted on the frame of the machine which supports the shafts 22 of the squeeze rolls 22 By the adjustment of these stands the ends of the carrier teeth 23 can be adjusted to the proper distance from the carrier table below (not shown).

The teeth 23 of each set are cast in one long piece, preferably of brass, and several sets of them are held in place on the arms 14 by means of iron rods 24 fastened to the arms 14. by set screws or the like. The toothed strips 23 are also fastened to these rods by set screws, preferably, as usual. These teeth however that have just been described, do not constitute the entire carrier, as according to this invention a series of adjustable toothed sections 25 equal in numher to the number of toothed strips 23 are provided. Each of these sections is provided with a horizontal body piece 27 adapted to be secured to the side of one of the toothed strips 23 by means of two rods 28 and 28 passing through the device in a manner similar to the rods 24 and holding toothed sections 25 by set screws or the like. The rod 28 is always in the same place on the carrier, but the rod .28 can be placed either in holes 31 or in holes 32 therein, but always passes through holes 33 in the tooth sections 25. Each of these sections is provided with a single tooth 29 arranged to come parallel with the teeth 23 when the body 27 is located in proper position and with a forwardly inclined long tooth 30 projecting from the root of the tooth 29 to a distance in front of it. These parts are shown in Fig. 2 as in position for operating on short fibers the rod 28 being set in the holes 31 at the most forward point on the carrier so that they will come closest to the rolls 22. At this time the fixed rod 28 enters holes 34 in the toothed sections 25. \Vhen it is desired to operate on long fibers, however, the rod 28 is set in the holes 32 in the carrier and the rod 28 enters holes 35 in the toothed section 25 which brings the teeth 29 and 30 back a greater distance from the rolls, as shown in Fig. 3.

It will be understood that this carrier is driven so it can be run faster than the rakes or barrows with which it is intended to be employed. IVith this construction, it will be seen that the free end of the carrier can be adjusted up and down by means of the adjustment of the stands so as to bring it to proper height and that the reach of the carrier can also be adjusted forward and back by moving the toothed sections 25, thus providing for adjustment in both directions to take care of different kinds of fiber and different conditions of washing. Whatever the adjustment the guides, being inclined as stated, gradually raise the carrier by a recti linear motion as it approaches the rolls so that the fiber under it will be freed from the surface of the carrier table. This leaves it in suitable condition to be nipped by the rolls and drawn in without freeing it too suddenly or too fully.

Although I have illustrated and described a single embodiment of the invention, I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described but lVhat I do claim is 1. In a washing machine, the combination of a reciprocable carrier and press rolls to which it is adapted to deliver stock, and a series of removable fixed toothed sections located on the end of the carrier adjacent to said rolls, said toothed sections each comprising a downwardly extending tooth substantially parallel with the main teeth of the carrier, and an inclined tooth extending substantially from the root thereof forwardly toward the nip of the rolls, said carrier having means by which said toothed sections can be fixed thereto in a plurality of positions.

2. As an article of manufacture, a removable toothed section for a washing carrier, consisting of a horizontal body adapted to be attached to the carrier at two separate points and having a pair of relatively fixed teeth extending downwardly from the end thereof at different inclinations.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
